My diamondback outlook has a serious problem. I can keep it in check by nursing it, but whenever it is subjected to torrential downpours, the BB fills with water. I've already destroyed two sets of bearings and scored a spindle (all replaced) by not keeping an eye on it. Last time I rebuilt it myself instead of having the shop do it.
I used a kind of axle grease made for marine applications, such as boat trailer wheels. It works pretty well and it held up okay to this week's treacherous deluges. I popped the adjustable cup off tonight to see what I'd find. Lo and behold, plenty of water poured out. The grease is still in good shape, so I didn't do a complete clean and re-grease, I simply re-packed the non-drive-side bearings that I'd taken out, and liberally smeared more grease on the spindle.
My questions are this:
1) What kind of grease SHOULD I use? This stuff seems pretty good for what I'm doing, but I didn't see any recommendations anywhere.
2) How can I keep water from plaguing my BB housing? Disassembly and using an air compressor to blast out the water after every wet ride is not an option.
3) Would a cartridge BB work in my BB housing? I can get measurements if needed. Would a cartridge be that much more durable than what I'm using?
For what it's worth, the only time I have problems is after a commute in really heavy rain. I'm not sure if this water-repellent marine axle grease would have withstood the abuse, but after taking it apart, it looks like it probably would have kept things well-lubed even with the moisture lurking in there. I didn't feel like finding out if my bearings were going to die in the middle of my commute this week, though.
